Introduction:

This series is a self-developed new generation of wear-resistant three eccentric metal-sealed butterfly valves with two sealing structures: multi-layer stainless steel-to-metal and metal-to-metal seals, which are widely used in pipeline systems of metallurgy, electric power, heat, petroleum, chemical industry and so on, and can be customized according to different needs.

Features:

1、Using three eccentric structure. Valve plate sealing ring and valve body sealing ring almost no friction, open and close easily, with the more closed the tighter the sealing function.
2、Hd multi-level metal sealing structure, sealing effect is good, can reach bubble level sealing, absolute zero leakage.
3、HQ all-metal hard seal structure, sealing vice scour resistance, long service life.
4、Three eccentric structure of the valve sealing vice can be self-compensating. Whether in low or high temperature, have excellent sealing performance, and not easy to jam.
5、This series of butterfly valve valve plate adopts truss structure, high strength of the valve plate, large overflow area, small flow resistance, energy saving.
6、According to the user's needs, it can be installed vertically or horizontally.

Execution standard

Design and manufacture, flange connection, structure length, pressure test are in accordance with GB, GB/T, EN, DIN, ANSI, API standards.
